To all whom it may concern.'

Be it known that I, LOUIS BRUN, a citizen of the French Republic, and resident of St. Chamond, France, have invented certain new and useful Improvements in and Relating to Rotary Motors, of which the following is a specification.

This invention relates to an improved rotary motor.

The object of the invention is to provide a rotating cylindrical element, in which .operate a series of pistons, connected to simllar plstons operating in a similar cylindrical element disposed at an angle to the aforesaid cylindrical' element, whereby the reclproeating movement is converted into rotary 'details of construction and arrangement of parts which will be hereinafter described and particularly pointed out in the clalms.

In the drawings z-Figure 1 is a diagrammatic perspective view of my improved mo- Fig. 2 is an end view of the same. Fig. 3 is a view similar to Fig. 1 but illustrating each angularly dis osed pistn fo Y 4`1g. is a detail perspective view of a valve used in connection with my invention. Fi 5 is a horizontal section of a somewhat di erent form of the invention. Fig. 6 is a view similar to Fig-1, illustrating a further modification. h

Referring particularly to Figs. 1 and 2, h indicates a casting provided with a horizontal bearing g and. a vertical bearing g. Mounted in the bearing g is a shaft f on the outer end `of which is mounted a pulle i and at its oppositeend is 4a cylindrlcal e ement b 'formed withV a series of horizontal bores a', a2, and a,a parallel with the lon itudinal axis of the shaft and' with which `,communicate ports c', c2 and 0 respectively. Mounted to reclprocate 1n the bores are 1s` tons d', .d2 and d, formed with stems e e2 and es, the stems being shown to illustrate the operation of the invention, but in practice, each piston is of angular formation and its ends engage in the bores of two elements, as will be escribed later'on.

Mounted on the shaft f between the outer end of the cylindrical element. and the bearis a valve casin indicated in Fig. 4. with-aV semi-circular inlet passage Z on one side of the center of the shaft and with which communicates an lthe same elliptical '.hores.

i inlet pipe c. The valve casingis also provided on the opposite side of the c'enter of the shaft f, with a semi-circular passage m which communicates with an exhaust pipe m.. The passages Z, and m, coperate with the ports c', c2 and c:a so that as the cylindrical element is rotated as will be presently described, the motive fluid employed to operate the motor will pass throu h the passage Z, and the ports and will ex aust through said ports and the passa e m. Three pistons are shown in the rawings, but obviously any vnumber may be employed. These pistons are arranged in circular relation in the cylindrical element as shown in tive pistons I have shown in perspective view an inclined plane indicated at A, B, C and D, disposed at an an le of about 45. Let 1t be supposed that t e piston e is forced within its bore by the inclined plane,

exhausting the duid through port m. Fluid from the passage l, enters the ort c and drives it out against the incllned plane, hence causin the cylindrical element b to rotate, the en of the stem e traveling in an elliptical path indicated conventionally at A in Fig. 1. The lstems e2 and e follow path, the Huid successively forcing the pistons out, and the inclined plane causing said istons to rotate the cylindrical element an when the fluid is cut off b the valve the ports will communicate with the exhaust passage and the incline lane will force them back in the ow, letit be assumed that the stem of the piston d, moves in unison with the stem e' obviousl it would follow the same elliptical ath and consequently rotate the cylin ical element b', a valve casing similar to that shown in Fig. 4, being mounted on the shaft f adjacent'the bearing g. By this arrangement of parts the reciproeating movement of the lstons is converted into a rotary motion, wi out employing inpurpose of assisting in gaining an understanding of the movement ofthe parts and it will be understood this is solely illustrative.

Referring to Fig. 3 it will be observedy that'the pistons, indicated at d, {Z and d2 are common to both cylindrical elements which isin fact the manner in which the parts will be constructed, for as before stated the inclined plane between the stems of the piston is for the purpose of illustrating the movement. rEhe pistons al, d and d2 are bent to provide horizontal and vertical heads which .it in the bores of the two cylindrical elements. Obviously when the motive fluid simultaneously acts on the respective heads of any one of the angular shape pistons and forces the same from the cylindrical elements, it will rotate both cylindricalelements. The fluid in the bores of the horizontal cylindrical element acting on the piston rotates the vertical cylindrical element b, While the Huid in the bores of the vertical cylindrical element acting on the opposite heads will simultaneously rotate the horizontal cylindrical element b. By this means simultaneously rotary motion is imparted to both cylindrical elements, the relative angular location of the cylindrical elements, the circular disposition of the pistons in each element, serving to insure of the reciprocating movement of all the pistons being the same.

The motors may be coupled together to obtain greater power as shown in Fig. 5. in this figure the cylindrical elements are designated I, H', XII and 11H. The angular pistons t, t and t coperate With the cylindrical elements IH and HH, while the angular pistons, u, u andv u2, coperate with the cylindrical elements and Il in exactly the manner as that previously described. A valve casing g, having the necessary inlet and outlet passages is arranged adjacent the cylindricalelement HH and a similar casing p, with inlet and outlet passages is arranged adjacent the cylindrical element l. casing, o, with inlet and outlet passages is interposed between the cylindrical elements Il and HI, whereby to admit and exhaust the fluid. .The operation of this form of' the invention is exactly the samev as that before described, but *ofy course greater power is generated.

In the embodiment of the invention shown in Fig. 6, disks 'Z6-80 formed with stems f7- 79, having openings 83, are substituted for the cylindrical elements. Fitting on the stems are sleeves 78, which are moved by the fluid entering the openings 83. Ob-

viously when the sleeves are subjected lto the pressure of the fluid, the disks 76 and 80 and their stems, 77, 7 9 will be rotated, hence the shafts 74 and 8l will also rotate. The

shafts are mounted in bearings 74, and 82, formed in a casting 7 5.

`What I claim is:

l. motor comprising ahorizontal driven 1 clement formed wlth openings which extend entirely through said driven element, a horizontal shaft on which said driven element is mounted, a vertically disposed driven element formed with openings which extend entirely through the said vertically disposed driven element, a vertical shaft on which the vertically disposed element is mounted,l

rigid angularly disposed driving elements registering with correspondin openings in the horizontal and vertically dlsposed driven elements, a valve casin mounted on the horizontal shaft and bearing against the end of the horizontal driven element, said valve A casing having inlet and outlet ports with which the openings in the horizontal driven element are adapted to register, a valve casing mounted on the vertical shaft and bearing against the end of lthe vertically disposed drivenclement, said lat-ter valve casing having inlet and outlet ports with which the opening in the vertically disposed dri ven element is adapted to register, whereby when motive fluid is passed through the inlet ports in the casings the drivingelements will be reciprocated and the horizontal and vertically disposed driven elements will be rotated.

2. Amotor comprising a horizontal driven element provided with a plurality of stems, each of which is formed with an opening, a vertically disposed driven element provided with a plurality of stems, each of which is formed with an opening, a plurality of angular shape driving elements each of which is open at its ends, said open ends fitting over the stemsof the driven elements, and means for admitting motive duid to the openings to reciprocate the driving elements and to rotate the driven elements.

In testimony whereof It have hereunto set my hand in presence of two witnesses LOUIS BRUN,
